Identity of IgG3, lambda light chain is verified by subclass monoclonal antibodies and type specific polyclonal antibodies in immunoelectrphoresis and indirect ELISA assays.
IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections.
[1] IgG3 is the has a unique extended hinge region conferring greater flexibility
IgG3, λ from human myeloma plasma is purified by fractionation, ion-exchange and affinity chromatography.
Mammalian immunoglobins contain either lambda or kappa light chains.
